- The outermost region of the earth's atmosphere, consisting chiefly of ionized hydrogen. 地冕地球大气的最外部分,主要由电离的氢组成
- Mottled pink and brown areas are a combination of the cosmic dust and reddish emission from ionized hydrogen gas. 斑驳的粉红色和褐色区域是宇宙尘埃和电离氢气放射出的红光相结合的产物。
- The clusters of blue are young stars, and the pink areas indicate concentrations of ionized hydrogen. 那簇蓝色的是年轻恒星,以及粉红领域表明浓缩的电离的氢气。
- As the hot central core of the star is exposed, its radiation ionizes the ejected gas, causing it to glow in vibrant green (emitted by ionized oxygen) and red (ionized hydrogen). 当恒星中央高热的核心裸露出来时,其辐射会游离喷出的气体,发出绚丽夺目的鲜明绿光(游离氧激发)与红光(游离氢)。
- Further out, when the radiation from these hot young stars becomes too weak to ionize hydrogen, the gas and dust instead glows by reflecting the original blue light. 另外,当来自这些炽热的年轻恒星的射线减弱到不能将氢电离时,气体和尘埃通过反射本来的蓝色光线发亮。
